A lime digestion dosing and feeding device

Abstract

The invention discloses a lime digestion and dosing device, which comprises: a lime transportation unit, a lime digestion unit, a lime milk separation unit and a lime dosing unit; Inlet and outlet, the inside of the cylinder from the inlet to the outlet is divided into: buffer zone, homogenization zone, milk slag separation zone, slag removal zone and slag discharge zone; quicklime is digested into Lime milk sand water mixture, lime milk sand water mixture flows out from the discharge port; lime milk separation unit separates the lime milk sand water mixture flowing in from the discharge port into lime milk and lime slag; the lime feeding device is a The device is installed under the fine lime tank, and its lime outlet is located directly above the feed port of the lime digestion unit. The feeding device can be used to automatically feed materials to improve work efficiency and save labor.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a lime digestion dosing and feeding device. Background technique [0002] The existing lime digestion and dosing process generally adopts the following two methods: one is to hoist the refined lime from the warehouse to the lime milk preparation tank to make a lime milk solution with a concentration of 20%, and then use the pump to send the lime milk to the sewage acid , one-stage, two-stage, three-stage neutralization tank for neutralization. The second is to send the refined lime in the refined lime tank to the lime tank, where the refined lime is soaked in contact with water, and after a period of natural cooling, it is grabbed by a grab bucket to the intermediate warehouse, then washed with water and entered into the lime digester, and finally discharged through the slag discharge screw. Separation of lime slag and lime milk, lime milk is sent to the neutralization t...

AI Technical Summary

Problems solved by technology

Adopting the first digestion and dosing process uses refined lime, which leads to high cost and major defects of lime dust, and the second digestion and dosing process has the disadvantages of serious waste of lime, frequent equipment blockage, and high failure rate.

The existing lime dosing and feeding is done by hoisting or manually pushing the trolley, which has uneven feeding, time-sharing feeding, no continuity, and affects the digestion effect
